Gtr With Adj Cam Gears

[R.3.2.G.T.R]

hi guys,

im looking at getting a PFC for my GTR shortly and get it tuned with adjustable cams thats already installed (currently set a 0).. car is pretty much stock and running 13psi boost.. should i expect an increase in performance.. from mem i think its -2 inlet +4 exhaust or vice versa for GTR's? also getting hi-flow cat put in as well so hoping for better performance..

wot if only tuned the car with my chipped hks ecu.. how much roughly for a tune like this (in syd).. also workshop recommendation would be great as im new to the area..

Alot of questions.

1. If you aren't expecting a performance improvement why are you putting in adjustable cam gears? You will pick up some gains. The cams need to be moved closer together - so advance the inlet & retard the exhaust, not the other way around.

2. High flow cat probably wont make bugger all difference over a stock cat.

3. Just get it tuned with the PFC & don;t worry about messing with the HKS stuff.

4. NFI.

Come on Matt - bigger turbs and bigger injectors while you're at it.

You know you want to!! lol How's Esperance?

As djr81 says you will get some and its worth it but there is much more lurking around the corner.

LoL Lance,

Nah, don't want to spend more than that this year. That's just a start. Get the most out the standard engine.

I really would like some turbos and such.........but you know how it goes. Esperance is pretty good at the moment, got quite a few blokes coming out of the woodwork now that I have got THE GT-R, starting to get them all together and go out for power cruises. Few more skyliners and other modified vehiculars.

As for the topic:

Power FC for the win. So many other people are using it and have such good results, plus you can't beat the plug in ability and the support for it out there, heaps of workshops will be able to tune it.

The adjustable pulleys are good for fine tuning the engine - ever heard of freak engines that just go! This should help get closer to that. Also good for adjusting your rev range properties on more modified cars. Best results will probably be obtained when you tune the cams and PFC together at the same time to suit each other.

yer i bought my adjust cam gears along with the greedy timing belt on my car and changed my water pump and my tesioners while i was at it, i got it tuned when i got my pfc all together, the cam gears will make a difference if you are getting the pfc put in and running 13psi and gave me 235.2kw at 4 wheels, but with the cam gears and the pfc will give your car quicker spool but 4 a top end they are not all that, highflowed cat wont do anything well maybe will but you want feel no difference because i got it on my car and better to have an exhaust fron turbo back (dumpipes, front pipes) then u will feel something, goodluck
